Abstract

OBJECTIVE: To evaluate the safety of combining salivary gland onabotulinumtoxinA (BTX-A) injections for sialorrhea with intramuscular BTX-A injections for spasticity in the same procedure. DESIGN: A retrospective cohort study in a tertiary hospital center. Patients selected were younger than 20 years, diagnosed with cerebral palsy, and received their first salivary gland BTX-A injection between March 2011 and July 2015. Chart review and telephone interviews were performed. The primary outcome measure was the rate of adverse events after combined BTX-A injections into salivary glands and muscles. The secondary outcome measure was the efficacy of injections, as reported by patients. RESULTS: Twenty-five of the 52 selected patients received salivary gland BTX-A injections only, and 27 received concurrent salivary gland and multi-level intramuscular chemodenervation with BTX-A with or without alcohol. The rate of adverse events was < 10% in both groups; 4% in 'Salivary Only Group' and 7% in the 'Salivary + Multilevel Intramuscular Chemodenervation with BTX-A group (with or without alcohol)'. Both approaches were equally effective in meeting their goals of salivary injections (> 50% improvement for at least two months). In the 'salivary only' and in the 'salivary + multi-level intramuscular' group, 76 and 85% of the patients reached their goals respectively. CONCLUSIONS: Combining BTX-A injections for sialorrhea with multilevel intramuscular BTX-A injections (with or without alcohol) appears to be safe and effective and allows treatment of patients for both conditions simultaneously.
